He hit the dude, but didn't kill him. I was merely refuting your "never misses" statement.
1 arrow and 3 arrows all bounce off a metal shield just the same.
The equestrian fighting is an idea that Zelda's creator has had for years, but could never do because of technology restraints. Legolas wasn't really a big horseman fighter either, in the movies at least he did once on the road to Helm's Deep (he got off pretty early too) and in the last charge in Helm's Deep. He rode a horse to get around, but doesn't everyone? 😉
Ok, the object here is for Legolas to hit Link in the head. Not the shield, the head. Not an easy thing to do against someone as good as Link, seeing as the shield's almost as big as he is. And Link has a bow too. And the Fire Rod/Ice Rod.
Link has much more close range stuff than Legolas. MASTER SWORD and a shield, hammer, bombs, Din's Fire, you name it. Plus, Link also has invulnerability magic. And the Fierce Deity mask. And the Giant's Mask. And a BOOMERANG!!!
